The food vs. feed competition is the competition for resources, such as land, between growing crops for human consumption and growing crops for animals.[1][2]
In many countries, livestock graze from the land which mostly cannot be used for growing human-edible crops, as seen by the fact that there is three times as much agricultural land[3] as arable land.[4]
The term food vs. feed competition is also used in the livestock industry to compare crop inputs (including space required) vs. protein outputs. For example, crops for people to eat require less land and other resources than crops for animals to eat so people can eat them.[5]
In a circular agriculture system, wasted food (no longer edible by humans) can be provided to livestock, which in turn feed humans.[6]
